Answer: 29

Explanation:

The variable amount is given a initial value of 0

Therefore, the first method call:

cookieJar(7)

amount + cookieJar

amount = 0 + 7 = 7

And the value of 7 is returned for amount at the start of the block

Thus, when cookieJar is called the second time ;

cookieJar(22)

amount + cookieJar

amount = 7 + 22 = 29

And the value of 29 is returned for amount at the start of the block

Negative numbers are encoded using the __________ technique. a. two’s complement b. floating point c. ASCII d. Unicode
OLEGan [10]

Negative numbers are encoded using the two’s complement technique. Two's complement is used to encode negative numbers.

Option  A is correct .

<h3>What method does the in data type use to store negative numbers?</h3>

Most implementations you're likely to encounter store negative signed integers in a form known as two's complement. Another important way of storing negative signed numbers is called one's complement. The one's complement of an N-bit number x is basically defined as x with all bits inverted.

<h3>What is encoding method?</h3>

An encoding technique is the application of established industry conventions to a coded character set to create a coded character scheme. Such rules determine the number of bits required to store the numeric representation of a given character and its code position in the encoding.

Brianna is taking a backpacking trip in the wilderness and wants to back up the photos from her camera. Which type of storage de
Katen [24]

Answer:

<u><em>C</em></u>

Explanation:

Flash drives usually have an input (E.G. one of those android charger connectors), so just plug that into your camera, and load the flash drive with the photos. Then go home and plug the USB on the flash drive into your PC. If there isn't already, a folder will be made in your "Pictures" folder on your PC, to which you can open the folder, and then your photos should be there. From there you can open them, print them, etc.

Hope this helped, and sorry if I didn't answer in time.

The information provided in text aids can help us to understand a text’s content before we even read it.
dimaraw [331]
It is true that the information provided in text aids can help us to understand a text's content before we even read it.
These text aids will contain bits and pieces from the text, which will make us understand the overall message even before we actually get down to going through the text itself. I believe it is better to actually read the text, and try to understand it on your own, before going to these aids for help.

Write the function longest that, given a nonempty list of strings, finds the longest even-length string that ends with ing. It t
lorasvet [3.4K]

Answer:

  1. def longest(L):
  2.    for x in L:
  3.        if(len(x) % 2 == 0):
  4.            if(x.endswith("ing")):
  5.                return x  
  6.    return ""
  7. print(longest(["Playing", "Gaming", "Studying"]))

Explanation:

The solution is written in Python 3.

Firstly, create a function longest that takes one parameter L as required by question (Line 1).

In the function, create a for loop to traverse through each string in L and check if the current string length is even (Line 2 - 3). If so, use string endwiths method to check is the current string ended with "ing". If so return the string (Line 4-5).

At last, test the function by passing a list of string and we shall get the output "Gaming".

A proper divisor of a positive integer $n$ is a positive integer $d &lt; n$ such that $d$ divides $n$ evenly, or alternatively i
juin [17]

Answer:

The program written in Python is as follows:

<em>See Explanation section for line by line explanation</em>

for n in range(100,1000):

     isum = 0

     for d in range(1,n):

           if n%d == 0:

                 isum += d

     if isum == n * 2:

           print(n)

Explanation:

The program only considers 3 digit numbers. hence the range of n is from 100 to 999

for n in range(100,1000):

This line initializes sum to 0

     isum = 0

This line is an iteration that stands as the divisor

     for d in range(1,n):

This line checks if a number, d can evenly divide n

           if n%d == 0:

If yes, the sum is updated

                 isum += d

This line checks if the current number n is a double-perfect number

     if isum == n * 2:

If yes, n is printed

           print(n)

<em>When the program is run, the displayed output is 120 and 672</em>
